action处理多个事务
处理多个业务 时候要使用dispatchAction如图所示
另外在parameter里面设置参数名称method。
共以后Action里面使用。

public class RegisterAction extends DispatchAction {
public ActionForward addUser(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
RegisterForm registerForm = (RegisterForm) form;
System.out.print("adduser");
return null;
}
public ActionForward updateUser(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
RegisterForm registerForm = (RegisterForm) form;
System.out.print("updateuser");
return null;
}
}
复制Exeute方法，生成业务Action同事去掉Exeute.不去的话form会默认找到他。
在form表单里面修改如下
<html:form action="/register">
uname : <html:text property="uname"/><html:errors property="uname"/><br/>
upass : <html:text property="upass"/><html:errors property="upass"/><br/>
<html:submit onclick="forms[0].action='register.do?method=addUser'"/><html:cancel/>
</html:form>
<html:form action="/register">
uname : <html:text property="uname"/><html:errors property="uname"/><br/>
upass : <html:text property="upass"/><html:errors property="upass"/><br/>
<html:submit onclick="forms[1].action='register.do?method=updateUser'"/><html:cancel/>
</html:form>
顺便贴个美女养眼
